Hi there ... This is actually not an A2Billing issue, but an Elastic billing issue but I couldn't see another forum to ask the question... Here's the thing: If a customer makes a voip call... you see it in the Elastix reports section from, say, the Caller id to the calling number. If then, after 2 minutes, the customer internally TRANSFERS the phone to another extension, I note that the call entry for the first part ends after 120 seconds and a new one starts between the caller id and the internal extension that RECEIVED the internal transfer, but not the calling number. When calculating the billing, I therefore have been missing these calls as being external, since they only show up as internal ... In this snippet - Extension 603 is external number 12345 making an SIP call to UK mobile 0777xxx. After 182 seconds 603 transfers to 601. Note that 601 does appear to call 0777xxx at anytime. As you can see the transferred segment looks like an internal call .... 2009-01-14 21:51:26 12345 0777xxxx SIP/603-b75ce0c0 SIP/Magrathea-b7604898 ANSWERED 182 2009-01-14 21:54:36 12345 0777xxxx SIP/603-b75ce0c0 SIP/Magrathea-b7604898 NO ANSWER 0 2009-01-14 21:51:26 12345 601 SIP/Magrathea-b7604898 SIP/601-b7a75a40 ANSWERED 276 2009-01-14 21:59:17 12345 601 SIP/Magrathea-b7604898 SIP/601-b7a75a40 NO ANSWER 0 Any ideas on what I can do to pick this issue up when billing ???
